Also referred to as optimum lot size, the economic order quantity, or EOQ, is a calculation designed to find the optimal order quantity for businesses to minimize logistics costs, warehousing space, stockouts, and overstock costs. The formula is: EOQ = square root of: [2(setup costs)(demand rate)] / holding costs.

## How do you calculate EOQ?

## What is EOQ graph?

The ordering costs – once you factor in the cost to create, place, validate, track, receive, etc – comes to $20 per order.

## What is the difference between EOQ and EPQ?

The EOQ model assumes that the product is easily available in the open market. Its replenishment will happen as soon as it reaches the minimum threshold level. Similarly, the EPQ model assumes that the production capacity is aligned with the requirements.
